Short-eared Owls are aptly named because they do have short ear tufts, hardly visible except when in a defensive pose.
They are medium-sized, with a large, round, pale facial disk bordered in white. Their eyes are yellow and outlined in black. Their bills are short, hooked, and black.
Their backs and wings are light and dark brown and white mottling. The upper breast is heavily streaked with dark brown, but the chests and bellies are pale or buffy. Their tails are also barred with dark brown.

Habitat And Diet
You can find Short-eared Owls everywhere in the world except for Antarctica and Australia. They particularly like uninhabited areas since they nest and roost on the ground, such as open prairies, coastal grasslands, tundra, marshes, and dunes.
Unlike most owls, Short-eared Owls hunt during the day, mostly at dawn and dusk, timing their hunt when voles are especially active.
They fly low over the ground looking and listening for movement from their prey of small mammals such as voles and mice.
They also eat birds like gulls and shorebirds, and usually take off the wings of the birds before they eat them.
Short-eared Owls Calls:
They are relatively quiet, but they make a series of continuous hoots and also scream, bark and whine.
Nests of Short-eared Owls are built by scraping the ground into a bowl and lining it with grass and soft feathers. They are usually concealed among tall grasses and low plants, and the female lays four to seven eggs but may lay more if their prey is abundant. Incubation is around four to five weeks.
Short-eared owls are not very vocal, but during courtship, the males will make about a dozen hoots, and they may bark, whine or scream when defending the nest.
